The Keyhole in the Carina Nebula
14.08.2016

The dark dusty Keyhole Nebula gets its name from its unusual shape. The looping Keyhole, in this featured classic image by the Hubble Space Telescope, is a smaller region inside the larger Carina Nebula.

NICER at Night
1.06.2019

A payload on board the International Space Station, the Neutron star Interior Composition Explorer (NICER) twists and turns to track cosmic sources of X-rays as the station orbits planet Earth every 93 minutes. During orbit nighttime, its X-ray detectors remain on.

The Lively Center of the Lagoon Nebula
1.06.2020

The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. A tremendously bright nearby star, Hershel 36, lights the area.

AR2835: Islands in the Photosphere
2.07.2021

Awash in a sea of incandescent plasma and anchored in strong magnetic fields, sunspots are planet-sized dark islands in the solar photosphere, the bright surface of the Sun. Found in solar active regions, sunspots...

APOD: 2026 April 17 Б M82: Starburst Galaxy with a Superwind
17.04.2026

Messier 82 is a starburst galaxy with a superwind. In fact, through supernova explosions and powerful winds from massive stars, the burst of star formation in M82 is driving a prodigious outflow. Evidence for the superwind from the galaxy's central regions is clear in the sharp telescopic portrait.

A Jet from Galaxy M87
6.07.2000

What's causing a huge jet to emanate from the center of galaxy M87? Although the unusual jet was first noticed early in the twentieth century, the exact cause is still debated. The above recently released picture taken by the Hubble Space Telescope shows clear details, however.

Gomezs Hamburger: A Proto Planetary Nebula
7.08.2002

What, in heaven, is that? Sometimes astronomers see things on the sky they don't immediately understand. In 1985 this happened to Arturo Gomez, and the object became known as Gomez's Hamburger for its distinctive yet familiar shape.

Apollo 14 Deploys ALSEP
10.12.1995

After the lunar module of Apollo 14 set down on the Moon, Astronauts Alan Shepard and Edgar Mitchell deployed the Apollo Lunar Surface Experiments Package (ALSEP) and collected samples of lunar material. The ALSEP scientific experiments included a seismometer sensitive to slight lunar surface movements, and charged particle detectors which measured the solar wind.

Europa s Freckles
1.11.2002

Europa, one of Jupiter's large Galilean moons, may well posses an ocean of liquid water hidden beneath its icy surface -- and so holds the tantalizing possibility of life. In this image, constructed with...

NGC 1275: A Galactic Collision
5.05.2003

In NGC 1275, one galaxy is slicing through another. The disk of the dusty spiral galaxy near the image center is cutting through a large elliptical galaxy, visible predominantly on the lower left. Galaxies...
